- n. The region of space through which the solar wind extends.
- n. astronomy The region of space where interstellar medium is blown away by solar wind; the boundary, heliopause, is often considered the edge of the Solar System.
- n. the region inside the heliopause containing the sun and solar system
“The heliosphere is immensely strong and extends far beyond the orbit of the dwarf planet Pluto.”
“Inside what is known as the heliosphere, the pressure from the energetic stream of charged particles emitted by the sun exceeds that in interstellar space.”
“It slows as it begins to collide with the interstellar medium, and the point where the solar wind slows down is the termination shock; the point where the interstellar medium and solar wind pressures balance is called the heliopause; the point where the interstellar medium, traveling in the opposite direction, slows down as it collides with the heliosphere is the bow shock.”
“The boundaries of the heliosphere is the location of the limits of my experimental range.”
“At the perimeter of the heliosphere is the heliosheath, a turbulent region at the outer edge of the solar system.”
“This solar wind inflates a giant bubble in interstellar space called the heliosphere -- the region of space dominated by the Sun's influence in which the”
“We have gotten to the point where the wind from the Sun, which until now has always had an outward motion, is no longer moving outward; it is only moving sideways so that it can end up going down the tail of the heliosphere, which is a comet-shaped-like object," said Dr Stone, who is based at the California Institute of Technology in Pasadena, California.”
“This solar wind inflates a giant bubble in interstellar space called the heliosphere -- the region of space dominated by the Sun's influence in which the Earth and other planets reside.”
“The IBEX mission just completed the first global maps of these protective layers called the heliosphere through a new technique that uses neutral atoms like light to image the interactions between electrically charged and neutral atoms at the distant reaches of our Sun's influence, far beyond the most distant planets.”
“The heliosphere is a bubble of magnetism springing from the sun and inflated to colossal proportions by the solar wind.”
